There are two main questions that arise from the assignment content. The first question is whether Ben is vicariously liable for the acts done by Colin, which means that one person is held responsible for another's actions during the course of employment. However, in this scenario, it is argued that Ben should not be held liable as there was no authorized act by Colin that harmed Roger's life. The second question is whether Mark can sue Regent Hotel for negligence and vicarious liability. It is concluded that Regent Hotel did not breach its duty of care to Mark, and therefore, it should not be held liable. Additionally, there was no master-servant relationship between Mark and Ben, which means that Ben cannot be held vicariously liable for Mark's actions.
